Class Sensor

java.lang.Object
  rcx.Sensor

public class Sensor
extends java.lang.Object

Sensor - encapsulates access to RCX Sensors
This class is based on leJOS's class of the same name

Before using a sensor, you should set its mode and type with setTypeAndMode using constants defined in SensorConstants.

Example:

Sensor.S1.setTypeAndMode(SensorConstants.SENSOR_TYPE_LIGHT, SensorConstants.SENSOR_MODE_PCT);

static Sensor[]	SENSORS

Constructor Summary

Sensor(int id, RCXPort port)
creates a sensor where id is 0, 1 or 2 for the specified RCX port

Method Summary

void	activate() not used (for compatibility with leJOS class of the same name)
int	getId()
void	passivate() not used (for compatibility with leJOS class of the same name)
boolean	readBooleanValue()
int	readRawValue()
int	readValue()
static void	setPort(RCXPort port) creates the static instances S1, S2, S3
void	setPreviousValue(int aValue) reset canonical sensor value, useful for rotation sensors
void	setTypeAndMode(int aType, int aMode) Sets the sensor's mode and type The default type is LIGHT and the default is PERCENT.

Constructor Detail

Sensor

public Sensor(int id,
              RCXPort port)

creates a sensor where id is 0, 1 or 2 for the specified RCX port

Method Detail

setPort

public static void setPort(RCXPort port)

creates the static instances S1, S2, S3

readValue

public final int readValue()

readRawValue

public final int readRawValue()

readBooleanValue

public final boolean readBooleanValue()

getId

public final int getId()

activate

public final void activate()

not used (for compatibility with leJOS class of the same name)

passivate

public final void passivate()

not used (for compatibility with leJOS class of the same name)

setTypeAndMode

public final void setTypeAndMode(int aType,
                                 int aMode)

Sets the sensor's mode and type
The default type is LIGHT and the default is PERCENT. (note: mode can be OR'd with slope (0..31) )

Parameters:

aType - 0 = RAW, 1 = TOUCH, 2 = TEMP, 3 = LIGHT, 4 = ROT.

aMode - 0x00 = RAW, 0x20 = BOOL, 0x40 = EDGE, 0x60 = PULSE, 0x80 = PERCENT, 0xA0 = DEGC, 0xC0 = DEGF, 0xE0 = ANGLE
